Hello

I am trying to insert APDL code in mechanical workbench model. It is a 2D axisymmetry model. I have created a Named selection for an edge. When I call that named selection using CMSEL, it is giving me an error in solution.

Hi,
This error ususally occurs if CMSEL command is not defined in /PREP7. Make sure to define CMSEL command as:
/PREP7
CMSEL, S,
....

I hope this helps.

I have defined /PREP7 command before CMSEL, still the same error

Hi

In order for forum members to be able to give feedback - can you show some screenshots of youyr model, apdl command snippetts, etc.

So more information will help members to help/advice.

Also try to resolve the model and see if it works.

All the best

Here are some snippets. this is the edge which was given a name selection. And this is an 2D axisymmetric model

Hi

Where do u place this command snippet (show image)?

First nsll does not work in WB – it is an apdl command associated with APDL made geometry (you have not made it there – it is a WB geom.).

Also if you have it in H5 in the tree we do not need the /prep7 – if you use /prep7 which you have done, then you need to add /SOLU in the end.

Second try and rerun as I said and see if it works.

Hello,

I have added /SOLU command at the end. I tried it by removing both /prep7 and /solu, still gave the same error

last try, can you send a picture of all the details with the named selection called LAYER -

so show details of LAYER

[Erik Kostson]

Not sure what is going on - perhaps someone else has some more ideas.

Try and resolve and Check in the ds.dat file to see that LAYER is written to the input ds.dat file.

[sahith.bandi]

Yes, included both in the snippet

[Erik Kostson]

Try and resolve and Check in the ds.dat file to see that LAYER is written to the input ds.dat file.

See here how to open the input file:

We can not replicate this issue. So we would need your model (can not attach it here).

I would suggest to send your model to our Ansys support – just open one (support request) up and we will try and see why this happens in your model.

All the best

Erik
